We need two definitions.
Two shapes are congruent if you can turn one into another using translation, rotation, and reflection.
Two shapes are similar if you rescale one them into a shape that is congruent to the other.
We can conclude from this that in euclidian geometry all circles are similar.
We can shrink the first circle to get the second one.
Scale factor would be 1/3 as circle 1 has the radius that is 3 times the radius of circle 2.

Answer: =3x^3+8x&2+ 85 /3 x+5

Step-by-step explanation:

3x3+8x2+20x+25 ÷ 3x+5

= 3x^3+8x^2+20x+25/3 x + 5

= (3x3)+(8x2)+(20x+ 25/3 x)+(5)

=3x^3+8x&2+ 85 /3 x+5

Alex787 [66]

³/14 cup of Debbie’s

Step-by-step explanation:

⁴/7 of ¾ is;

⁴/7 * ¾ = 12/28

= ³/7

Each friend gets ½ and ½

Therefore ½ of ³/7 is;

½ * ³/7 = ³/14

= ³/14 cup of Debbie’s

How do I find the product when multiplying with decimals<br><img src="https://tex.z-dn.net/?f=0.36%20%5Ctimes%202.4" id="TexForm

Step 1:

first let us convert the two decimals into fractions.

0.36=36/100 (since there are two digits after decimal point we divide by 100)

2.4=24/10 (since there are one digit after decimal point we divide by 10)

now we can multiply the fractions

$\frac{36}{100}$ × $\frac{24}{10}$

multiplying numerator with numerator and denominator with denominator:

$\frac{36*24}{100*10}$

= $\frac{864}{1000}$

Now we can convert this back to decimal

864/1000=0.864, moving decimal three digits to the left since we have three zeros in the denominator that is 1000.

Answer=0.864

What is 42.735 to nearest one

7nadin3 [17]

Answer:

43

Step-by-step explanation:

.735 is greater than 0.5, so you round it up to 43. If it was, say, 42.335, then you'd round it down, because 3 is smaller than 5.

Answer:

$y = 1x - 4$

Step-by-step explanation:

You have to solve for the x intercept on the equation

$2x-5y=8\\2x-5(0)=8\\2x=8\\x=4\\(4,0)$

That is the x intercept for that equation.

Then solve for the y intercept on the equation

$4x-3y=12\\4(0)-3y=12\\-3y=12\\y=-4\\(0,-4)$

That is the x intercept for that equation.

Use that to find slope for point slope form

$\frac{y_{2}-y_{1}}{x_{2}-_{1}} \\\\\frac{-4-0}{0-4} \\\\\frac{-4}{-4} \\\\1$

1 is the slope

and slope makes B the y intercept so the equation is

$y = 1x - 4$
